Chris Brown to Rihanna — I OWN YOUR ‘P****’!!!

Exclusive 030813_chris_brown_club_launchChris Brown has a message for Rihanna … and any other guy who might want a piece of her … back off, because “THAT IS MY P**SY!”

Chris was partying at Emerson Theatre in Hollywood early Thursday AM when he grabbed the mic from the DJ and went off on how to talk to your woman — and the bizarre rant was all caught on tape.

Chris said, “You GOTTA say that one thing to her … Don”t make me have to tell you again, that”s my p***y baby! … so you better not give it away!”

Chris rambled on … “So every person in this motherf**king building, if you got a bad bitch you better say that s**t to her, or she might f**k another n***a.”

Another girl tip … don”t beat your woman.
